9 - x < 8 => -x < 8 - 9 => -x < -1 => x > 1
9 - x > 3 => -x > 3 -9 => -x > -6 => x < 6
So the number is between 1 and 6, notation 1 < x < 6
#7
vertical x = 5
and
horizontal y=6
#8
vertical x = -2
horizontal y=-3
btw
#10: -10x - 3
#11: -5x -3
Answer:
x < 21
Step-by-step explanation:
to solve this - 3 ( x - 5/3 ) <26 inequality
- 3 ( x - 5/3 ) <26
- ( x - 5) = 26
x + 5 = 26
x = 26 - 5
x = 21
therefore x < 21
7/40
La fraccion de Alemanes son 35/200=7/40
